[Gate-users] Forbid command, activity distribution

[Parisa Khateri]

Hi Philip,

I assume the first case is correct, i.e. 1 MBq would be distributed over a smaller volume.

Cheers,
Parisa

Dear GATE-community,

I have a rather simple question that I could not find the answer in neither the mailing-list nor the documentation.

Consider the case where I create a box with arbitrary dimensions, and I create a volume gps source with the same dimensions as the box and assign the source an activity of say 1 MBq. If I then would create a daughter inside my box and utilize the forbid command on that daughter, would the activity of 1 MBq now be distributed over a smaller volume of the mother box (i.e. Volume_mother - Volume_daughter) resulting in a higher activity concentration, or would the same activity concentration as in the case where no forbid command were utilized apply (i.e. same activity concentration over a smaller volume)?

Best regards,
Philip
